Hello guys, i was having this wierd behavior of my laptop where battery woudnt charge above 6%, ive tried most of the "solutions" on the web, but none of them worked. -Desinstalling Microsoft's ACPI-Compliant control method battery -Doing a vista clean install -Restarting/Removing/Plugging the battery from the laptop with the system running and shut down, and all sorts of combinations between. -Trying different AC (from dell, some of my friends have got some dell systems, i tried a m1330 AC) -Tried to find a battery calibrator, but was unsuccesful, and even tried to downgrade my BIOS, but couldnt because my battery wasnt charged above 10% (thats a requisite to flash the BIOS) NONE OF THOSE WORKED. So i called dell, they told me to go to the BIOS, tech guys told me that the problem could be figured out there by 2 ways, it'd either: -Recognize the AC adapter (in due case, it was a battery problem) -Or it wouldnt recognize it (in which case, it would be a MoBo or a AC adapter problem. Turned out it recognized the AC adapter, so next step was to send me a new battery, since i had a 6 cell battery (which the dell guy confirmed after i gave him the serial number of the battery) i expected to receive a 6 cell battery replacement, but no, lucky me i received a 9 CELL BATTERY INSTEAD, free within warranty period (system is only 7 months old) so yeah, im happy, and my battery is charging again. Everything is fine, so i thought i would share this info for you guys. One thing to get in consideration: The embedded battery health indicator might not indicate that the battery is healthy, since my faulty battery had 5/5 green lights when i tried to check the health but was still faulty (my new one has 5/5 health lights and works wonderful) Have a nice day.
